  1. Val,

    If you want to get rid of some, let me know.

    Thanks,

    Leon

    Congrats!

    I just cleaned out my cannister tonight and got quite the nice surprise. I found 16 baby plecos inside! I didn't even know my plecos were breeding :P They are already about 1cm so I have no idea when they were born. They are so cute though!!! :wub: I can only imagine how cute a whole tank full would be.

  2. I know I haven't been on here a lot lately. All the Africans are doing well, and I was too busy developing the basement. Now that it is almost finished, I have decided to give saltwater a try. I bought a 120 Perfecto with a corner overflow. I will be custom building the stand and canopy. I also purchased the 4 lamp T5HO from AquaticLife. I hope to find a good tank for the sump. Something with a 36"x18" footprint.

    Now I need suggestions on:

    -Skimmer brand and size

    -Return pump brand and size

    -All Live rock vs. some live and some base rock

    -Sump layout. I have some idease from the net, but it's cool to see other ideas.

    That's all for know. Future questions on stocking and compatibility to follow.

    Thanks,

    Leon

  3. I am running three 1200's for undergravel jets and I have had one impeller fail. This was after about three years in service. I do agree that they are not very strong. And to buy a new impeller is not cheap. I usually wait for the Boxing Day sales, and pick up a couple new units for close to the same price.

  4. Ok...........now you have made an assumption that is not correct. Yes skyscrapers are held together with bolts. But they are not stood on top of bolts. I am a structural steel detailer. So I work with bolt capacities all the time.

    Bolts have a capacity rated in shear strength and tensile strength. Shear is the resistance 90° to the bolt or across the diameter. The loading capacity changes with whether or not the threads are included or intercepted in the grip of the bolt. Tensile is the resistance to pull along the length of the bolt or stretch. A bolts tensile strength is a bit higher than its shear strength. And then there are slip-critical connections where the clamping action of the bolts causes enough friction between the connected parts that they hold together.

    You mentioned that there are 1" thick nuts on the inside of the endcap. Are these fully welded or tacked to the plate? This weld is in tension. If they are indeed fully welded around each nut, you will have about 3/4" worth of thread (in the nut) to take the 833 lbs of load. The nut would be better place on the outside, so that it comes up against the endcap in bearing.

    Taking that all things are welded properly and you have at least 3/4" of thread usage, you will be ok.

    I will not say anything further.

  5. Dustin,

    I think you are missing the point. We are all aquarists with different ideas on how to build something or make things work with what we have. One of your other posts is about how expensive this hobby is. It would be an utter shame if you were to build this tank and have a $2 bolt be the demise of some wonderful inhabitants. Just being cautious. Take this advice however you like, and go what you think is best.

  6. Just a quick calculation. You will probably be up in the area of 5000 lbs. That's 833 lbs. per cap screw. How thick is the plate that you have threaded? What is the diameter of the cap screw? You can double the capacity by using a locking nut below the plate. Definitely needs to be looked at.

  7. Leon,

    I think they moved, or that address is wrong. I went driving around there and couldn't find them...When I called the number they told me they were at:

    305 116 Ave.

    Sherwood Park, AB

    You need to take 17 st. to get there, it's a little tricky.

    Oops, I think you may be right. The main plant is the address you gave. Just South of the Yellowhead at 17St and then East on the service road. Can't miss it.

    Last time I bought a bag, it was 40kg for $14.

    I am sure there is a distributor in Calgary as well.
